Вот схема:

<?xml version="1.0" encoding="UTF-8"?>

Что я хотел бы сделать, это создать XML с использованием модуля, созданного pyxbgen, но я понятия не имею, как. Примеры в документах pyxb мне не помогли.

Я попытался опубликовать модуль здесь, но он слишком большой.

Кто-нибудь может дать мне понимание, с чего начать хотя бы?

Большое спасибо!

Answer 1

У меня такая же проблема. Для загрузки исходного кода, пожалуйста, обратитесь к примеру ниже. Затем из основного репозитория перейдите на./examples/manual/demo2.sh. Я использовал git-версию PyXB-1.2.4.

пример:

cd to some_dir
git clone https://github.com/pabigot/pyxb.git
git checkout PyXB-1.2.4.

Затем перейдите в каталог.pyxb/examples/manual, чтобы посмотреть демоверсии.

Дайте мне знать в комментариях, если вам нужна дополнительная помощь.
